Product Description:

Type description

Take 350QZB-50 as an example

350: the nominal diameter of the pump

Q: submersible

Z: axial flow

B: semi-adjustable blade

50: 1/10 of the pump specific speed (take the integer part)

According to different pump specific speeds, the flow capacity range of this type of axial flow pump can reach up to 700m3-1400 m3

The principle of Axial flow pump is to lifting water according to the thrust caused by the impeller when rotating. Because water moves along the axial in the impeller, so we called it axial flow pump.

In accordance with its mode of installation, axial flow pump can be distinguished into three class: vertical, horizontal, inclined. Their structures are almost the same. Now the vertical form is used widely. The main accessories contains bell-mouthed pipe, impeller, guide blade, outlet syphon, shaft and bearing, stuffing box, etc.

Summarize of QZ series Axial flow pump:

Installation of water flow Channel: in terms of recommended sample installation diagram

The form of water exit: flap valve or other ways

Installation ways: suspended by bent pipe; suspended in well casing, etc.

Motor

Submersible motor

Power Level: electrical performance conforms to GB756

Protection level: IP68

Cooling method: ICW08A41

Basic installation form: IM3013

Voltage grade: ≤355kw, voltage,380v/660v; 355kw,voltage, 380v, 660v, 6000v, 10000v

Insulation level: F

Rated frequency: 50Hz

Length of cable: 10m

Shaft seal

There are two or three stages of mechanical seal. The first stage called carborundum (directly contact with water). The second and third stage called graphite and carborundum.

Leak proof Equipment

QZ, QH series pump have been equipped with leak proof sensors. When the oil tank, the inner part of motor or the junction box has been leaked by water, the sensor will signal or made the motor shut down, and retain the malfunction signal.

Over heating protection system

A overheating protection device is fastened on the motor winding. When the temperature exceeds the stated &#118alue, the device will signal or made the motor shut down.

Rotation direction:

Seen from the top of the motor, the impeller is rotating clock wisely.

Application

QZ series axial flow pump, QH series mixed-flow pump is widely used in industry and agriculture water lifting, urban water supply, light polluted water discharge and other water transfer project.

Working condition

Clean water with the temperature no more than 50 or some liquids that are similar to water.

Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
The little air hose is had to pump in pump operation, to play the role of oxygen, generally want to let the oxygen hose head above the water, or to go into the air, and lose the function of oxygen, if the tank is large enough, every day to open the filter pump. Use hose plus oxygen does not matter.
Q:Should my mechanic have changed thermostat with water pump?
Yes he should have replaced it. It was pretty stupid for him not to replace it. Everything was taken apart and the thermostat was right there. Now he's going to undo everything he did, have you pay more for gaskets and coolant, replace what he should have replaced in the first place and then put it back together while your without a car for a few more days. If I were you I'd find a competent mechanic.
Q:I have problems with an Espa water pump with a pressure vessel. It is very slow to cut in. Pressure gauge to 0
The guage is probably broken, but that is mostly for reference for setting your start/stop switch. Now, first off I'd check your bladder tank. A bad bladder tank will still give you some pressure but causes the pump to run almost constantly. To test that, there is a bicycle looking air valve sticking out of the bladder tank. Push a key or something in it as if you were to let air out of a tire. If any water comes out, your bladder is bad and has to be replaced. If you have an older style deep well, like a well house where the pump is accessible, check the switch, (little black box attached to the pump). There are two screws that can be turned. One sets the pressure the pump will turn off at and the other adjusts the minimum pressure you want for the water to turn back on and fill your tank. A lot of people go 20/40, I run mine at 30/50. Much more than that and you can run into problems, especially if you have cpvc pipes. They will weaken at the elbows and 60 psi of water can eventually make pin hole leaks. This is from personal experience. You will need a working gauge to set this. If the bladder is not your problem, email me and I'll give you more details on how to set your pump if you need it. Or, you can buy preset switches at your local hardware for $20 and just swap it out. In that case, do not mess with the adjustment screws.
Q:Integral Problem: Water is pumped out of a holding tank at a rate of 4-4e^-.14t liters/minute?
Water is pumped out of a holding tank at a rate of 4-4e^(-.14t) liters/minute. Lets call that function w(t). So if we integrate w(t) over a time period that will give us the total water removed over that time period. So lets integrate it from t=0 (time when pump started) to t=60 (one hour later): ∫ w(t) from t=0 to t=60 ∫ w(t)=∫ 4-4e^(-.14t)=4t+(4/.14)e^(-.14t) evaluated from 0 to 60 ∫ w(t)=4(60)+(4/.14)e^(-.14*60)-4(0)-(4/.1... ∫ w(t)=211.435 liters removed If the holding tank began at 1000 liters and 211.435 were removed... Remaining water=1000-211.435 ***Remaining water=788.565 liters***
Q:What is the reason that the water supply of pump is getting smaller?
1., first look at the external situation, to see whether the water pump is running, the water level is not normal, the water inlet has nothing blocked.2., exclude the external situation, or small water, the pump itself may leak, it will also make water smaller
Q:I have a small drip coming from the raw water pump, whats the problem?
Could be any one of a few things. If you're brave enough to taste it (just get some on your finger and touch the tip of your tongue), then you'll be able to tell if it's rainwater or engine coolant, which tastes sweet. If it's coolant, then your heater has a leak. More likely today is rainwater getting in round the windscreen seal or the sunroof, if it has one. Leaks are very difficult to trace and you might have to wait for a dry day, then remove all the carpets and sit in the car while someone aims a powerful jetwash around suspect areas.
Q:outboard motor not pumping water?
check the thermostat, it could be clogged.
Q:02 golf gti 1.8t water pump replacement?
The timing belt drives the Water Pump in a VW- ??????????????????? I don't think so. That said, it is under the timing belt and you must remove it to access the pump, heck you have to strip the entire front of the engine to get that bad boy out. I would order the Housing with the pump already installed and a new housing O-Ring and get new bolts. The reason is that the actual pump bolts tend to snap on removal and are next to impossible to drill out of the housing. My guess is a lousy install if it is leaking or substandard parts. ASE Cert Auto Tech, since 1978, 2003 GLI
Q:Do I need a water pump?
That's the common thinking (to replace a water pump if you go as far as removing the old timing belt. The idea is that if you don't replace it and it goes bad before the next time the timing belt needs changed, then you will pay significantly for the labor that could have been done now. Boy, I hate to hear those prices. I have always done my own repair work. Do you own the tools and capable/amenable to doing it yourself ? Do you know that if you did that job yourself that the cost would only be about $110. ($30+/- for the belt; and $80+/- for the pump). Anyway.... yeah replace the pump now if the mileage is 75,000 or more because it probably won't last until 150,000 (next belt change)
Q:Is it ok to drive a car with a bad water pump?
the water pump cycles through the engine and cools it to a safe level without it the water heats up and will start to boil you will blow a head gasket in a matter of a few blocks and it will do damage to almost everything in the engine DON'T DRIVE A OVERHEATING VEHICLE
